ABSTRACT Nanofibers of Al2O3 (commercial product NafenTM) with characteristic length of ∼100 nm and diameter of ∼10 nm were used to create new hybrid materials based on copolymer of ethylene and propylene. Nanocomposites were obtained by in situ catalytic copolymerization on the system rac-Et(2-MeInd)2ZrMe2/isobutylalumoxane. Formation of the nanocomposites with uniform distribution of Nafen nanoparticles in polymer matrix was confirmed by scanning and transmission electron microscopy. According to dynamic mechanical analysis data, introduction of the nanofiller in an amount of up to 3 wt % leads to an increase in glass transition temperature by 10 °C ( E″) and by 21 °C (tan δ). The nanocomposites exhibit improved physico-mechanical properties (tensile strength and elongation at break). It is shown that the nanofiller significantly improves resistance of the nanocomposite to the thermo-oxidative and thermal degradation. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
